Numerical simulation of fluid flow and alloy melting in RH process for electrical steels

Hai-jun Wang et al.

Summary: A mathematical model based on the Eulerian-Lagrangian approach was used to study the gas-liquid flow behavior in a RH degasser. The expansion of gas bubbles was found to have a significant impact on the recirculation rate and mixing time. Increasing the superheat of liquid steel and decreasing the initial diameter of alloy particles were found to enhance the melting and mixing processes.

Large Eddy Simulation on the Transient Decarburization of the Molten Steel During RH Refining Process

Chang Liu et al.

Summary: A mathematical model was established to describe the decarburization coupled with transient fluid flow in RH treatment. The periodicity of the flow field was analyzed using the large eddy simulation (LES) model. By taking 13 seconds as the flow field period, the flow field information stored in user-defined memory was repeatedly read in order during the calculation, enabling the coupling of the transport of [C] and [O] in molten steel with the LES model and greatly reducing the calculation time.

Simulation and Application of Ruhrstahl-Heraeus (RH) Reactor with Bottom-Blowing

Jianfeng Dong et al.

Summary: The study focused on increasing refining efficiency in steelmaking by blowing extra gas into the Ruhrstahl-Heraeus (RH) reactor through the bottom, which showed that increasing bottom-blowing flow rate led to higher recirculation flow rate, shorter mixing time, and effects on the flow field of the molten bath, slag eye formation, and snorkel refractory materials. The optimal bottom-blowing flow rate and position improved refining effect without adverse effects, shortening processing time by 16.40% and increasing dehydrogenation rate by 19.51%.

Summary: CFD is an effective tool for studying transfer phenomena in the RH system. The T-WCM model developed in this study shows better prediction results for carbon mass concentration compared to the O-WCM model. The presence of CO gas in the system significantly affects the multiphase flow, mass transfer, and reaction rate, leading to a more precise description of the gas-liquid flow and decarburization process in RH.

Effect of Drag Laws and Turbulence Models on CFD Modeling of the Bubble Behavior and Fluid Flow in RH Reactor

Qing Cao et al.

Summary: Different drag laws and turbulence models were compared to evaluate gas distribution and fluid flow velocities in an RH reactor. The study found that Morsi's drag law predicts more accurate local velocity compared with other laws, and turbulent dispersion plays a significant role in predicting gas-liquid flow in a RH reactor. Additionally, while LES approach predicts more realistic free surface fluctuation, the realizable k-epsilon model shows better agreement with measured local velocity in the furnace.
